SECTOR-SHAPED CARTON.

SPECIFICATION forming part of Letters Patent No. 756,494, dated April 5,1904.

Application filed August 24, 1903- candy or the like in pails and whichare made of a single flat blank cut to the proper shape and having itsparts joined by the use of paste or glue to form a tubular body andconnected bottom wall, which may be folded fiat for transportation, butwhich may be readily set up for use.

The invention consists in the matters hereinafter set forth, and moreparticularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 illustrates a blank for forming acarton madein accordance with my invention. Fig. 2 is a perspective Viewof the carton when folded and ready for use looking upwardly at thebottom thereof. Fig. 8 is a perspective view of the carton when foldedand ready for use looking downwardly into the interior of the same. Fig.4 is a side view of the carton when the parts thereof are joined bypasting and the same is folded flat for transportation. Fig. 5 shows theblank after the ends of the tubular part or body-have been joined bypasting and when the folding flaps or sections which constitute thebottom are in their extended or unfolded position.

The blank illustrated embraces four connected main sections A B (l D,which constitute the tubular body of the finished carton and areseparated by score-lines (0b 0 d, an end or pasting flap E, joined tothe section D and separated therefrom by a score-line cl, two triangularbottom-sections F and Gr, of which the section F is connected with themain section B and the section G is connected with Serial No. 170,514.(No model.)

an extension of the bottom flap G. The gusset-sections H and I areseparated from the body-section C and bottom-section F by scOrelines 71and 2' and from each other by a scoreline it. The gusset-section J isseparated from the bottom-section G by a score-liney' and from thegusset-section K by a score-line is. On the bottom margin of thebody-section A is a pasting-flap L, separated therefrom by a score-lineZ, and on the bottom margin of the body-section Dis a pasting-flap M,which is separated from the same by a score-line m. The bottom-sectionsF and G are alike in shape and together correspond in form with thebottom of the carton, and said sections constitute the bottom wall ofthe carton when the same is ready for use, as clearly seen in Figs. 2and 3. The gusset-sections H and I are also alike in shape and arejoined to and fill the triangular space between the bottom margin of thebodysection C and the adjacent margin of the bottom-section F, the sidemargins of said gusset-sections (indicated by the score-lines l1 and i)being of corresponding length, while the score-line it, which dividesthe Said gussetsections H and I, subtends the angle between saidscore-lines h and c'. The gusset-sections J and K correspond in shapewith the said sections H and I, the side margin of the section J, whichjoins the section G, being of the same length'as the side margin of thesection I, which joins the section F, while the score-line la subtendsangle between the scoreline j and the corresponding outer margin of thesection K. The sections A and B constitute the diverging walls of thesector-shaped carton, while the sections 0 and D form the outer or arewalls thereof, the width of the sections C and D being equal and theunited widths of the sections B and C being equal to those of thesections A and D. The parts of the blank thus made are permanentlyjoined or pasted by folding the section D along the score-lines 0against the section C and likewise folding the section A along thescoreline (4 against the section D and then securing the pasting-flap Eto the outer margin of the section A. The parts will then be in the position shown in Fig. 5. The sections Gr,-I, and K are then foldedupwardly and against the sections F, H, and J along the score-line g andthe pasting-flap M then pasted to the margin 7a of the section K and theflap L on the section A also secured to the adjacent margin g of thebottom-section G. The parts will then be in the position shown in Fig.4, the blank then being in its knockdown or folded form and ready forshipment or transportation.

In setting up or placing in readiness for use the blank shaped, folded,and pasted in the manner described the sides of the tubular body of theblank are spread apart by drawing apart the same at the score-lines dand 6, this movement tending to straighten out the bottom-sections F andG. Before the body of the blank I reaches its fully-expanded form,however, and

while the said bottom-sections F and G still stand at an angle to eachother the triangular connecting parts or folding gussets formed in oneinstance by the gusset-sections H and I and in the other instance by thegusset-sections J and K are folded upwardly into the interior ofthe'carton, this being accomplished by pressing inwardly on the parts atthe scorelines h in. The gusset-sections are in this operation foldedtogether or against each other along the said score-lines it and in, andsaid gusset-sections are bent into angular relation to the parts withwhich their outer margins are connected on the score-lines h d and jm.After the triangular gusset-sections J K and H I have thus been foldedinwardly the side Walls are drawn farther out and the bottomsections Fand-G pushed upwardly until said gusset-sections J K and H I are pressedflat against each other and rest closely against the upper or innersurfaces of the sections F and G, as clearly seen in Fig. 3, when thecarton will be in condition for use.

'It will be understood that the bottom of the carton made as describedwill be of ample vented by the contents of the carton, but becausedownward pressure coming on the inturned gusset-sections J K and H Iwill have little effect in forcing downwardly or out- Wardly thebottom-sections, in view of the fact that the sections K and H aredirectly attached to the Walls C and I) and are support ed by said wallsfrom downward movement, as will be readily understood from an inspectionof Figs. 2 and 3.

I claim as my invention 1. A blank for sector-shaped cartons embracing abody portion which is divided transversely by score-lines into four mainsections adapted to form the radial Walls and are walls of the cartonand is provided on two of said sections with a flap for forming thebottom of the carton consisting of two triangular sections, shaped toconform to the bottom of the carton and two pairs of gusset-sectionsforming extensions of the two triangular bottomsections adapted to befolded inwardly inside of the bottom-sections; thesaid blank also havingpasting-flaps for joining one of the bottomsections to one of thebody-sections and for joining one of the gusset-sections to one of saidbody-sections.

2. A sector-shaped carton comprising two radial walls and two are Walls,which walls are joined to form a tubular body, a bottomwall embracingtwo triangular bottom-sections which are joined to each other and to theradial walls of the tubular body, and two triangular pairs of foldinggusset-sections, each pair of which is attached at one edge to one ofthe bottom-sections, and at its other edge to one of the arc walls ofthe tubular body.

In testimony that I claim the foregoing as my invention I affix mysignature, in presence of two Witnesses, this 15th day of August,

JOEL C. GRAHAM. Witnesses:
